Specification of Letters Patent.

Patented July 4, 1916.

To all whom it may concern:

Be it known that I, EDWIN A. ROONEY, a citizen of the United States,residing at Fairhaven, in the county of Bristol and State ofMassachusetts, have invented the following described Improvements inCoiler-Fronts for Cards.

The invention is an improvement in coiler front apparatus for dividedcards, whereby each of the many subdivisions of the card fleece can beuniformly and practicably condensed and coiled in individual sliver cansfrom which cans they can be run directly into a Slubber or coarse rovingframe without intermediate doubling or drawing.

WVhile the invention and particularly certain features thereof can beused with divided cards producing only four divisions of its fleece, itis more particularly adapted for use with cards producing eight or moredivisions or fleece sections.

In certain respects the invention is an improvement on the structuredisclosed in application Serial N0.'740,971, filed January 9th, 1913, byElwin H. Rooney, the object being to simplify and enhance theconvenience of use of said structure through a certain method ofgroupingor arranging the sliver cans and the distributing and coilermechanism, as hereinafter set forth, so that the operator may moreconveniently reach the said cans as well as the doffer and deliverymechanism of the card without disturbing the uniformity of treatmentwhich each sliver must receive.

In the accompanying drawings, Figure 1 is a top plan view of a portionof a divided card with one form of the invention applied thereto. Fig. 2is a side elevation of Fig. 1. Fig. 3 is a top plan of a modifiedarrangement. Fig. 4 a side elevation of Fig. 3. Fig. 5 is a top plan,with parts in section, of the can stands for the form of Figs. 1 and 2.Fig. 6 is a similar view of the can stands of the form shown in Figs. 3and 4. Fig. 7 is a section through the table surface and calender rollsof either form.

The doffer cylinder marked 1, may be regarded as the dofi'er of anysuitable card adapted to produce a fleece in the form of numerous narrowstrips or' ribbons,herein termed fleece sections. For this purpose thecylinder in the present case is divided by a series of tapes 2, whichdivide the fleece formed thereon into a plurality of fleece sections,eight in number in the machine illustrated. These fleece Sections areremovedv from the cylinder by an oscillating dofl'er comb 3, which, asobserved in the drawings, operates at the front side of the cylinder sothat any dirt it liberates may fall to the floor and not on thecylinder. As the present lnvention is largely concerned with theeconomical working of cotton Waste containng more or less dirt, theadvantage of locating the doffer comb at this point is obvious. From thedoffer comb each fleece section passes immediately into one of thetrumpets 4, which are mounted in a cross-plate 5, eX- tending across thecard directly in front of the comb. The cross-plate and its trumpets areset substantially at the same level as the doffer comb, so that thefleece sections are sub ect to the least possible attenuation in movingto the trumpets. A set of rolls operates directly in front of thetrumpet nozzles drawing the condensed fleece sections therethrough anddelivering them from the card. In the present case these rolls are madeup of a single bottom roll 7 (dotted lines Fig. 2) which is driven by agear train 8 from the dofler wheel 9 of the card, and a set of top rolls10 resting by gravity upon the bottom roll and held in place thereon bymeans of the crotch supports 11. All the top rolls 10 are of the sameweight and each serves two adjacent fleece sections, pressing equallyupon each of them. A Weighted clearer 6, (Figs. 1 and 2) of any suitableform is placed on the top rolls 10. This clearer is omitted from threeof the rolls as shown in Figs. 1 and 3. The rolls and their trumpetscooperate to condense the very tenuous and narrow fleece sectionsdischarged by the dofl'er comb so as to enable them to be elevatedsafely to the level of the entrances to the cans into which they are tobe coiled. The gear train 8 on the card also drives a cross shaft 12,suitably supported in brackets 12 on the overhanging ends of the cardframe, and whichserves as the driving member for the parts of the coilerfront mechanism, driving the section-com veying mechanism of the latterthrough the two inclined shafts 13 and the coiler apparatus through thetwo upright shafts 14, both of which are bevel geared to said crossshaft 12 near its center.

The coiler front mechanism according to this invention is divided intotwo or more sections which maybe symmetrical duplision consists ofadistributing mechanism or table structure set on legs resting on thefloor or otherwise supported in front of the card so as to accommodate agroup of onehalf or one-third, or a portion, of the number of slivercans, beneath it. Said structure is elevated above the level of thedoffer and delivery means of the card so as to accommodate cans of largecapacity and standard diameter and each is also equipped witha -seriesofpairs of calender rolls or other means for-elevating the fleecesections,

from the level of the condensing mechanism,

to the level of the cans and conveying and depositing them in thelatter, as well as with meansfor coiling the sections in the cans.

The calender rolls are driven by one'of the shafts 13 and the coilermechanism by one of the shafts 14. WVhen the distributing mechanism isdivided into two divisions, as in the case illustrated, they aredisposed in front of the sides of the card so as to leave anintermediate central space between them, in which the attendant mayapproach the card to attend to the piecing of the middle fieecesectionsor for other purposes' If three or more divisions are formed, similarspaces are left between them, such spaces being either for access to thecard or for removal of the cans.

Inthe form of Figs. 1- and 2, the table structure constituting eachdivision of the distributing mechanism is, of greatestdimensio-n foreand aft of the card and of least dimension crosswise of the card and isalso somewhat wider near the card than at the opposite end, so as thusto accommodate the convergence of the fleece sections, as indi cated inthe drawings, with the least obtrusion into the space left for theoperator. The top surface of the table structure is de sirably smoothand at its end nearest the card turns downwardly forming the apron 16inclined toward the card delivery. The sections are drawn upwardly overthis apron and along or over the upper surface of the table, by means ofthe condensing'rolls 17 and 18, which also draw the sections through thetrumpets 20 in the covers 19, thereby imparting a second condensation toeach section. The lower rolls 17 are carried in or "below openings inthe table structure, on'

shafts 21 driven by bevel gear connections with a shaft 22, which lattergears with one of the inclined shafts 13 above referred to, beingthereby driven in unison with the card. The cover 19 bearing the trumpet20 is hinged to the table structure so that it can be turnedupwardlywhen desired to uncover the roll opening, and the upper roll 18 is heldin place on the lower roll by means of supports 18 which are covered bytotal which the cans rest orinany other suitable way by which thesections will be boiled in the cans so as to prevent snarling whenremoved.

vFig. 5 shows a can stand for the form of Figs. 1 and 2, 23 being .aninclosing casing which can be secured to the floor between the legs ofthe table structure, and 24 being the individual can stands, eachsecured to a gear 25, the set of these gears being intergeared by idlers26 and driven by a gear train 27 from the upright shaft 14 abovereferred to, the lower end of which is stepped within said casing. Asthus arranged the can stands 24 are driven by the card at a uniform rateof speed-and each can rotates eccentrically to the calender rolls 17 and18. The distributing mechanism of this form is shown as accommodatingfour cans arranged in a single row extending away from, and parallelwith the card. Additional cans may be added to the row as desired, themanner of grouping remaining the same.

Referring to Figs. 3'ancl 4, the card structure will be understood to bethe same as that of Fig. 1, being designated by the same referencecharacters. The sections oflthe distributer and coiler mechanism eachcomprise a table structure 28 mounted on legs as in the preceding casebut adapted to accommodate a double, instead of a single row of slivercans thereunder. The upper surface of this table structure is alsoprovided with an inclined apron 29, like the apron 16, of the form firstdescribed and is also slightly wider near the card than at its oppositeend to accommodate the convergence of the fleece sections. The calenderrolls 17 and 18 with their covers 19 and trumpets 20 are the same as thecorresponding parts in the other form, but are arranged two abreast, sothat every other fleece section may move to the calender rolls nearestthe card and the alternate sections to the rolls farthest from the card.The driven rolls of each pair of rolls aremounted on a common shaft 30beneath the table'which is driven by the card through an inclined shaft13. The sliver cans are set on rotary stands 31, the same asthest'ands24, but arranged in a double row, extendingaway from the sidesof the card and inclosed in a similar casing can stands permits accessto the card in the same manner as in the case of the form firstdescribed.

It will be observed that whether the cans are grouped in single ordouble rows, the space between groups will be sufficient not only toadmit the attendant but also wide enough to permit him to remove orinspect any one of the cans without touching or disturbing the others.
